Alternative Cooling Method Advice Needed

jeff80 · 02-15-2003, 07:18 AM

OK - need some serious advice from the gurus of extreme cooling.

My current system is a basic dangerden 2-2 waterblock(not using the attachable cold-plate cause I've not decided on peltiers yet), 1/2" hoses, a reservoir, a small cube radiator and although it's adequate in keeping my Palomino 1600+ XP @ 1.75ghz/1.85v, I want have a much better cooling system that would be able to get me MUCH lower cpu core temps under load.

I was thinking about maybe getting into phase-change cooling akin to the Prometeia cooling system, or for a cheaper cost - a dual TEC solution. Would that give me better cooling?

This is what I'm planning to do in the next 2 months:

For the Dual TEC setup:
Dangerden Maze2-2 waterblock with 1/2" barbs
Dual 174watt Peltier @ 18v
Two 24v power supplies powering the TECs
Danner Model 5 Pump
Lytron 6340 Heatercore *HUGE*
1/2" tubing all around

Due to the size of the Lytron Heatercore, would passive cooling work with this heatercore, or would I need to attach a few fans to the heatercore for efficient cooling. It really is HUGE....

What kind of temps will I get with this setup on a Palomino 2100+ @ > 2ghz, @ ~2.0v Vcore?

Should I instead opt for the prometeia cooling system. Will that provide me with superior cooling power? I mean, the dual TECs can dissipate over 350watts of heat, so should that not be enough to keep a 2ghz Palomino at sub-zero temps, and should that not provide me with better results than the prometeia system?

Thanks for all the help guys.

I would get the prommy, not just because it is cooler but also because it consumes less electricity, is smaller and more efficient and not as loud.

The prommy isn't difficult to install

don't stack pelts whatever you decide to do

If the TEC's are the same as what I think they are 172W @ 24V with a max delta T of about 69C.

First yes they can move 350W @ 0deg C dT. Second at 18V and cooling a 70W (just a round number as an example) load under great conditions (20C water temp) you could expect to get about 5 to 10 C at the CPU. (straight out of kryotherm's calc).

Just a simplistic model to let you know what to really expect.

why not?

A 172W pelt puts out 230+W of heat. Another 172W pelt on top of that one will be way overloaded. That is why you don't stack pelts, you put them physically next to each other.

well, that kinda makes sense. what about stacking a 226w on top of a 172?

murray13 · 02-20-2003, 03:05 PM

It would still be overloaded.

ok, so on most athlon socket chips, how do you fit the peltiers next to each other?? generally there doesn't seem to be that much space on these boards
